Can a non-CEC Inverter be connected to the Australian grid?

Lets use a Victron Multi RS Solar PMR482602020 as example

Report date: 11 February 2026 (Australia/Brisbane)

Scope: Whether the Victron PMR482602020 (Multi RS Solar 48/6000/100-450/100) can be legally/technically connected in parallel with the Australian distribution grid when it is not on the Clean Energy Council approved inverter list (“CEC-approved” in common installer shorthand). This report focuses on electricity-network connection rules and published DNSP requirements. Local council/planning rules are not assessed (unspecified; varies by council and local planning schemes).

General information only — not legal advice. Always confirm with the local DNSP and state/territory electrical safety regulator before purchasing or installing equipment.

This report was compiled with the help of Artificial intelligence on 11/02/2026, it should not be used other than to do your own research, to assist you in your own research, you must verify all claims made here, by the AI before proceeding, and you should be a qualified person to perform any electrical work.

Executive summary

In Australia, the entity that decides whether an inverter energy system may be connected to the distribution grid is the local distribution network service provider (DNSP) via the connection application/offer and connection agreement — not the Clean Energy Council (CEC). However, in practice, DNSPs overwhelmingly require inverters to be on the CEC Approved Inverter List (or equivalent “approved/onboarded” lists derived from it), because CEC listing is the most common way DNSPs verify compliance to the relevant inverter standards (especially AS/NZS 4777.2). Many DNSPs also build their application portals so that installers can only select inverters drawn from the CEC-supplied list.

Consistent with that, every major Australian DNSP reviewed in this report publishes a requirement that grid-connected inverters be CEC-listed (or “CEC approved”), with only two DNSPs (Ausgrid and Endeavour Energy) explicitly publishing a pathway for a “CEC unlisted inverter proposal” via written approval. Even under those “written approval” pathways, the inverter still needs to meet the technical requirements (AS/NZS 4777.2/4777.1 and DNSP-specific settings/controls), and DNSPs warn installers they may be required to replace non-compliant inverters at their own cost if installed without meeting requirements.

For the Victron PMR482602020 specifically, Victron’s own public documents for the Multi RS Solar show extensive international certifications, but do not show an AS/NZS 4777.2 certificate on the product’s certificate list, and the product datasheet’s standards list also does not include AS/NZS 4777.2. By contrast, Victron does publish AS/NZS 4777.2 certification for some other models (e.g., MultiPlus-II), demonstrating what an Australian certificate looks like. This strongly suggests the Multi RS Solar PMR482602020 is not presently certified/listed for Australian grid-parallel connections. (It may still be suitable for off-grid or generator-only use, but that is a different compliance pathway.)

Bottom line: if your PMR482602020 is not CEC-listed, you should assume it will be rejected for grid connection by most DNSPs. The only realistically arguable pathway is a case-by-case written approval with a DNSP that explicitly allows proposals for CEC-unlisted inverters (published only for Ausgrid and Endeavour Energy), supported by full third‑party compliance evidence and any DNSP communications/export-control requirements. For all other DNSPs, the published position indicates no non-CEC pathway for new grid-parallel connections (unless an exemption is explicitly published by a government technical regulator for a defined purpose, such as South Australia’s dynamic export regime — and those exemptions are time- and model-specific).

Legal and regulatory framework

Who has the “yes/no” authority to connect to the grid?

The practical permission to connect comes from the DNSP connection process: you apply (often via an installer portal), receive a connection offer/approval subject to conditions, and connect/commission in accordance with that agreement and the DNSP’s technical requirements. Some DNSPs state explicitly that approval is only granted after entering into a connection agreement, even for zero-export systems.

Where does the CEC “approved inverter list” fit?

The CEC is not the grid connection decision-maker, but its “Approved Inverter List” is the key reference dataset used across Australia. The CEC itself describes permitted API use cases including “Network Service Providers confirming that an inverter is listed on the CEC’s Approved Inverter List prior to connection”, which is an unusually direct statement of how the list is used in DNSP practice.

The CEC’s inverter listings are also structured around evidence of compliance: the CEC notes that model numbers with an “(AS4777-2 2020)” suffix indicate approval supported by an AS/NZS 4777.2:2020 certificate issued by a JAS‑ANZ accredited certifier or state electrical regulator. Separately, Energy Networks Australia notes that most DNSPs use the CEC approved inverter listing as their approved product list and many use it to populate their customer portals.

Why CEC listing matters even beyond DNSPs: STCs and the Clean Energy Regulator

If the installation is intended to create Small‑scale Technology Certificates (STCs) under the Small‑scale Renewable Energy Scheme, the federal Clean Energy Regulator states that newly installed small generation units must have their panels/batteries/inverters listed on the CEC list of approved components (among other requirements). So a non‑CEC inverter may not only jeopardise DNSP grid approval; it can also remove STC eligibility (which impacts economics and retailer finance).

AS/NZS 4777.2 and the National Electricity Rules context

The inverter behaviour standard at the centre of Australian grid‑connected DER is AS/NZS 4777.2. AEMO explains that AS/NZS 4777.2 specifies expected low‑voltage inverter performance/behaviour and compliance tests, and links compliance to secure operation under high DER penetration. AEMO also describes work with the Clean Energy Regulator and the CEC to incorporate inverter settings checks into CER inspections, reflecting enforcement attention on not just hardware certification but actual commissioning settings.

Multiple DNSPs explicitly describe AS/NZS 4777.2 as “mandated by the National Electricity Rules” in their installer guidance. For example, Ausgrid and Endeavour Energy state that AS/NZS 4777.2:2020 (‘Inverter Requirements’) is mandated by the National Electricity Rules. SA Power Networks also references National Electricity Rules amendments commencing 18 December 2021 requiring grid-connected inverters to comply with AS/NZS 4777.2:2020.

AEMO DER Register: an additional compliance “paper trail”

Australia’s DER Register (operated by AEMO) is a national database of installed DER devices; AEMO explains it launched in March 2020 and that DER device information is typically requested from installers/contractors at installation time. DNSPs commonly require installers to submit DER details within 20 days of commissioning, and DNSP pages in NSW explicitly reference this requirement and provide installer contacts.

Verification of the Victron Multi RS Solar certification status

What Victron publishes for the Multi RS Solar

On Victron’s public Multi RS Solar product page, the “Certificates” section lists multiple country/region certifications (e.g., VDE‑AR‑N 4105, EN 50549 variants, IEC safety standards, etc.). The list shown does not include an Australian AS/NZS 4777.2 certificate for the Multi RS Solar.

The Multi RS Solar datasheet lists technical specifications and a “STANDARDS” line showing safety and EMC standards (e.g., IEC 62109, IEC 62040, IEC 62477) but does not list AS/NZS 4777.2 in that standards block. The datasheet also shows the unit’s PV characteristics (450 V open-circuit maximum, MPPT operating range up to 450 V, and PV input current limits), but these electrical specs do not substitute for Australian grid‑connection certification.

What an Australian AS/NZS 4777.2 certificate looks like for Victron (comparison)

Victron does publish an Australian certificate example for other products: a “Certificate of Suitability” (issued by SGS Australia under a JAS‑ANZ accredited scheme) for MultiPlus‑II models that explicitly lists compliance including AS/NZS 4777.2:2020 (and related standards). This demonstrates that Victron’s public documentation can include Australian certification where it exists.

Implication for grid connection

CEC listings commonly rely on recognised certification evidence (including JAS‑ANZ accredited certification or state regulator certification) and distinguish AS/NZS 4777.2:2020 compliant models via the “(AS4777-2 2020)” suffix. If the Multi RS Solar lacks AS/NZS 4777.2 certification evidence, it is difficult to see how it could be accepted for grid‑parallel connection under DNSP rules that require CEC listing.

DNSP implementation in Australia

Coverage and summary chart

The table below covers the standard electricity DNSPs for the ACT, NSW, VIC, QLD, SA, TAS, WA and NT (the same DNSPs consumers typically see on their network/distributor details). Chart: DNSP published requirement for CEC-listed inverters (Australia-wide, reviewed DNSPs) Total DNSPs reviewed: 16 ■ CEC required (no explicit non-CEC exception published): 14 (87.5%) ■ Conditional (CEC or explicit “written approval” pathway for unlisted inverter): 2 (12.5%) 14 2

Interpretation note: “Conditional” here means the DNSP’s published guidance explicitly offers a written-approval pathway for a “CEC unlisted inverter proposal”. It does not mean the DNSP accepts uncertified equipment; technical compliance still applies.

Interpretation notes on the table:
1) “CEC approval required” means the DNSP’s published guidance requires selection of a CEC‑listed inverter (or defines “approved inverter” as one listed on the CEC list), or requires the inverter be CEC‑registered/approved as a grid‑connect inverter. In Victoria, several DNSPs additionally require the inverter to be “onboarded” to the DNSP’s utility server (CSIP‑AUS / IEEE 2030.5 context).
2) “Conditional” is used only where the DNSP explicitly publishes a “written approval” pathway for a CEC‑unlisted inverter proposal (Ausgrid and Endeavour Energy).
3) Some technical documents use the word “should” for CEC registration; however, DNSP portals, related installer guidance, STC rules, and emergency backstop/dynamic export regimes frequently make CEC listing a practical prerequisite to approval and commissioning.

So can PMR482602020 be grid-connected if it’s not CEC-approved?

For a grid-parallel connection (exporting or capable of exporting in normal operation), the published DNSP position across Australia is effectively “no”, unless a DNSP explicitly grants an exception. Most DNSPs state their inverter must be CEC-approved/registered, and their portals and commissioning regimes (CSIP‑AUS onboarding, utility server capability tests, export limiting, regional settings) are built around that assumption.

In NSW, Ausgrid and Endeavour Energy are notable because they explicitly publish a written‑approval pathway to propose a CEC‑unlisted inverter. That pathway is not automatic approval: it simply means the DNSP is willing to assess the proposal. If assessed and rejected (or if installed without meeting requirements), the installer may be required to replace the inverter at their own cost. Given the Multi RS Solar’s apparent lack of AS/NZS 4777.2 certification evidence in Victron’s public materials, obtaining approval would likely require strong third‑party certification evidence and DNSP-compatible control/communications.

For non-export / off-grid configurations: Many standards and DNSP rules treat systems as “grid connected” if they can operate in parallel with the distribution system; true off-grid or break-before-make changeover arrangements may fall outside embedded generation connection rules, depending on design. This is highly technical and jurisdiction-dependent — if the intent is any form of grid interaction, assess it with the DNSP and a suitably licensed electrician/engineer before purchase.

Practical steps for installers and system owners

Before you buy or install (the “don’t get stuck with an unconnectable inverter” checklist)

  • Identify the DNSP first (your distributor). Use regulator resources (AER) or check the electricity bill.
  • Confirm the inverter is on the CEC Approved Inverter List (and check the listing is current/not expired). Also confirm the correct AS/NZS 4777.2 standard version and regional setting apply.
  • Confirm state/DNSP-specific mandatory controls:
    • Victoria: emergency backstop / CSIP‑AUS utility server onboarding requirements are explicit for several DNSPs.
    • Queensland: emergency backstop mechanism / Generation Signalling Device requirements are documented for certain systems.
    • South Australia: dynamic export capable equipment/commissioning tests and timelines are governed by government technical regulator guidance and SA Power Networks processes.
    • Western Australia (SWIS): Western Power requires Australia Region B settings; CEC listing is used to deem compliance.
    • Horizon Power: SGD compatibility list and hardwired comms to DERMS are mandatory for relevant connection classes.
  • Confirm STC / rebate implications early: if STCs are part of the commercial model, check the Clean Energy Regulator eligibility rule requiring CEC-listed components.

If you still want to pursue a non-CEC inverter grid connection

In practice, this only makes sense where the DNSP explicitly allows an “unlisted inverter proposal” pathway (published for Ausgrid and Endeavour). For those DNSPs, engage before purchase and be prepared to supply:

  • Independent certification evidence to AS/NZS 4777.2 (current applicable version) and anti-islanding evidence (IEC 62116), plus installation compliance to AS/NZS 4777.1. DNSPs commonly require an accreditation number and/or recognised test evidence.
  • Evidence that the unit can be configured to the DNSP required regional settings (Australia A/B/C) and that those settings are locked/verified.
  • Evidence of compliance with communications/export control obligations if applicable (CSIP‑AUS/IEEE 2030.5, utility server connectivity, capability tests, fallback export behaviour).
  • A clear single-line diagram and export-limiting method (where limited export applies), plus any commissioning test report required by the DNSP.

If you cannot supply the above, the probability of approval is low, and installing anyway risks forced replacement and/or inability to legally energise/export.

Post-install obligations that commonly apply

  • AEMO DER Register submission (commonly within 20 days of commissioning), either by the installer or via DNSP-integrated workflows depending on jurisdiction.
  • Commissioning evidence: many DNSPs require commissioning sheets/capability test results and validate certificates of electrical safety before enabling metering / export.

Alternative compliant ways to achieve a Victron-based system

If the goal is “Victron ecosystem + legal grid connection”, the simplest path is to choose a CEC-listed inverter/charger or hybrid inverter suitable for your topology and DNSP requirements, and confirm listing status before purchase. Victron has published AS/NZS 4777.2 certification for some products (e.g., MultiPlus‑II certificate shown), and many other mainstream brands are listed on the CEC approved inverter list used by DNSPs and STC eligibility rules.

Important: “CEC-approved” can mean different things in casual conversation (installer accreditation vs product listing). Here it means the product is listed on the CEC approved inverter list used by DNSPs and STC eligibility rules.

How Lithium Prices Influence ESS-Grade LFP Cell Costs

Introduction

How Lithium Prices Influence ESS-Grade LFP Cell Costs Lithium iron phosphate (LiFePO₄ or LFP) is the chemistry of choice for stationary energy storage systems (ESS) thanks to its safety, cycle life, and cost stability.
But battery-grade lithium carbonate (Li₂CO₃) prices can move sharply. The big question: does this heavily impact the final cost of an ESS battery?
The answer: it has a surprisingly small effect — even when prices double.

1. Real-World LFP Cell Examples

Two widely used prismatic LiFePO₄ cells from EVE Energy are great case studies:

  • EVE MB31 – 314 Ah large-format cell (~1 kWh, ~5.6 kg)
  • EVE LF100LA – 100 Ah cell (~0.326 kWh, ~1.98 kg)

Exact lithium content is proprietary, but we can calculate it closely using LiFePO₄’s chemistry.

2. Lithium Carbonate Content in LFP Cells

Lithium makes up about 4.4% of LiFePO₄’s cathode mass, and lithium carbonate is 18.8% lithium by weight.

From this, manufacturing each 1 kWh of LFP storage capacity needs ~0.47 kg of lithium carbonate.

This means:

  • MB31 (≈1 kWh) → ~0.47 kg Li₂CO₃ per cell
  • LF100LA (≈0.326 kWh) → ~0.153 kg Li₂CO₃ per cell

3. Price Change: USD $10,000/t → USD $20,000/t

Let’s compare the impact of lithium carbonate doubling from USD $10/kg to USD $20/kg.

Per cell:

  • MB31 314 Ah:
    • $10/kg → USD $4.70 lithium cost
    • $20/kg → USD $9.40 lithium cost
    • Increase: USD $4.70 (~AUD $7)
  • LF100LA 100 Ah:
    • $10/kg → USD $1.53 lithium cost
    • $20/kg → USD $3.06 lithium cost
    • Increase: USD $1.53 (~AUD $2.30)

4. Effect on a 51.2 V Battery Pack (16 Cells)

Most 51.2 V ESS batteries are built from 16 cells in series:

  • Using MB31 cells (314 Ah / ~1 kWh each):
    • 16 × USD $4.70 increase = USD $75.20 (~AUD $112) more if Li₂CO₃ doubles in price.
  • Using LF100LA cells (100 Ah / ~0.326 kWh each):
    • 16 × USD $1.53 increase = USD $24.48 (~AUD $36) more if Li₂CO₃ doubles in price.

5. Why the Impact Is So Small

Even a 100% jump in lithium carbonate prices adds less than AUD $120 to a large 51.2 V / 314 Ah battery, and under AUD $40 to a smaller 100 Ah version.

That’s because:

  • Lithium carbonate is only a small fraction of the cell’s mass.
  • The rest of the cost comes from iron, phosphorus, graphite, copper, aluminium, electrolyte, casings, BMS, labour, testing, logistics, and installation.

6. Key Takeaways

  • Doubling lithium carbonate from USD $10k/t → USD $20k/t adds:
    • ~USD $75 (~AUD $112) to a large 51.2 V 314 Ah pack
    • ~USD $24.50 (~AUD $36) to a smaller 51.2 V 100 Ah pack
  • Other materials, manufacturing, and installation dominate ESS battery costs.
  • Lithium price swings are important, but they don’t make or break ESS battery affordability.

Cheaper Home Batteries Program Australia 2025

Step-by-step summary of the Cheaper Home Batteries Program policy paper and some rough cost comparisons to help you work out the best option for you:

1. Introduction and Context:

  • The Challenge: Australia leads the world in rooftop solar panel installations. However, the adoption of small-scale battery systems (which store solar energy for later use) is lagging. The primary reason for this is the high upfront cost of purchasing and installing these batteries.
  • Why Batteries are Important:
    • They help secure renewable energy resources by storing excess solar power.
    • They improve the overall reliability and stability of the energy system.
    • They allow households and businesses to maximize their use of self-generated solar power, reducing reliance on the grid and potentially lowering electricity bills.
  • Purpose of the Policy Paper: This document outlines the Australian Government’s plan to support the uptake of battery systems by making them cheaper. It details the key features of the “Cheaper Home Batteries Program,” focusing on who is eligible and how the program will work. It’s important to note that some details might change before the final regulations are approved.

2. The Cheaper Home Batteries Program: Core Details

  • Program Name: Cheaper Home Batteries Program.
  • Primary Goal: To significantly reduce the initial purchase and installation cost of small-scale battery systems for Australian households, businesses, and community facilities.
  • Start Date: The program is scheduled to begin on July 1, 2025.
  • Delivery Mechanism:
    • The program will be implemented by expanding the existing Small-scale Renewable Energy Scheme (SRES).
    • The SRES currently provides incentives for installing small-scale renewable energy systems (like rooftop solar panels) through the creation of Small-scale Technology Certificates (STCs).
    • The program will extend this STC mechanism to include eligible battery systems.

3. Financial Incentives (The Discount):

  • Target Discount: The program aims to reduce the upfront cost of an eligible battery system by approximately 30%.
  • Discount Value in 2025:
    • This 30% discount is estimated to be equivalent to $372 per kilowatt-hour (kWh) of the battery’s usable capacity.
    • In terms of STCs, this translates to 9.3 STCs per kWh of usable capacity in the year 2025.
  • Progressive Reduction: The level of discount (and therefore the number of STCs) will gradually decrease over time. By the year 2030, the discount is planned to be half of what it is in 2025. This is designed to encourage earlier adoption.
  • Funding the Discount: The Australian Government will purchase the STCs generated by the battery installations from the STC Clearing House. This government purchase effectively covers the cost of the discount provided to consumers.

4. Eligibility Criteria for Battery Systems and Applicants:

  • Who is Eligible? The program is open to:
    • Households
    • Businesses
    • Community facilities
  • Battery System Size:
    • Eligible battery systems must have a usable capacity between 5 kWh and 100 kWh.
    • However, the discount (STCs) will be provided for a maximum of 50 kWh of usable capacity per system.
  • Solar PV System Requirement:
    • The battery system must be installed in conjunction with a new or existing solar photovoltaic (PV) system.
  • Accreditation Standards:
    • Both the battery itself and the inverter (which converts DC power from the battery to AC power for household use) must be accredited by the Clean Energy Council (CEC). This ensures they meet certain quality and safety standards.
  • On-Grid vs. Off-Grid Systems:
    • On-Grid Systems: Batteries connected to the main electricity grid must be Virtual Power Plant (VPP) capable.
      • VPP Capability: This means the battery system can be controlled (with the owner’s permission) to work in coordination with other distributed energy resources (like other batteries or solar systems) to provide services to the electricity grid. This can help with grid stability, managing peak demand, and integrating more renewable energy.
    • Off-Grid Systems: Batteries not connected to the main electricity grid do not need to be VPP capable.
  • Relationship with Other Incentives: The support provided under this federal program will be in addition to any rebates or incentives offered by state and territory governments. This means consumers may be able to “stack” incentives for a greater overall discount.

6. Regulatory Framework and Administration:

  • Primary Administrator: The Clean Energy Regulator (the Regulator) will be responsible for administering the Cheaper Home Batteries Program as an expansion of the SRES.
  • Responsibilities of the Clean Energy Regulator:
    • Ensuring overall compliance with the program’s rules and regulations.
    • Validating applications for STCs related to battery installations.
    • Issuing the STCs once applications are validated.
    • Managing a system of inspections for installed battery systems to ensure they meet requirements.
    • Educating the industry (installers, suppliers) about the program.
    • Taking compliance and enforcement action if rules are broken.
  • Role of State and Territory Regulators:
    • State and territory government bodies will continue to be responsible for aspects related to:
      • Electrical safety of battery installations.
      • Ensuring installations comply with local electrical codes and standards.
      • Consumer protection issues related to the sale and installation of battery systems.

In summary, the Cheaper Home Batteries Program aims to significantly boost battery adoption in Australia by making them more affordable through an expansion of the SRES. It sets clear eligibility criteria focused on system size, solar integration, product accreditation, and VPP capability for on-grid systems, with the Clean Energy Regulator overseeing its implementation.

EVE 306AH VOLTAGE TO SOC

This information can tell us about LFP prismatic format cells and how the SOC to voltage works.
This data is pulled from an online resource, where an EVE MB30 cell was discharged at 40Amps of current from 3.6v to 2.5v.

The total capacity of this cell was approx 333ah and the average voltage was 3.23V throughout this 3.6-2.5v range.

Some important points. 10% was approx 3.09V under load. This is as low as we recommend taking the LFP cells to avoid any significant damage. Many users try to aim for the 20% point which cant really be achieved through voltage alone, a shunt or BMS with shunt like the JK Inverter BMS, would be needed to stop the battery at 20% SOC.

This will probably not be accurate, but under a load of about 0.2C the voltage of 20% SOC MB30 cells would be about 3.19V.

Identifying Qualified Solar PV and Battery Storage Providers in Queensland: A Guide to Current Standards and Verification

Accreditation for solar installers in Australia has recently transitioned from the Clean Energy Council (CEC) to Solar Accreditation Australia (SAA) as of May 2024

1. Introduction: Finding Accredited Solar & Battery Providers in Queensland

Navigating the process of selecting a solar photovoltaic (PV) and battery storage provider in Queensland requires careful consideration, particularly regarding qualifications and accreditation. Homeowners and businesses seeking to install these systems rightly prioritize safety, quality, performance, and eligibility for government incentives, such as Small-scale Technology Certificates (STCs). Ensuring that installers and designers meet specific requirements is crucial for systems to qualify for STCs.  

However, the landscape of accreditation and approval within the Australian solar industry has undergone significant changes recently. The term “Clean Energy Council (CEC) Accredited Installer,” once the standard, is no longer current. The responsibility for accrediting individual installers transitioned from the CEC to Solar Accreditation Australia (SAA) on 29 May 2024. Concurrently, the CEC’s “Approved Solar Retailer” program, which focused on businesses selling solar systems, was replaced earlier, in February 2023, by the New Energy Tech Consumer Code (NETCC) Approved Seller program. The CEC continues to administer this new code.  

This shift, involving distinct changes for both individual installers (now SAA) and retail businesses (now NETCC), introduces potential confusion for consumers. Businesses may still use outdated terminology like “CEC Accredited,” either intentionally or through oversight, making it harder for consumers to understand current requirements. This is compounded by the fact that these schemes cover different entities – SAA accredits individuals , while NETCC approves businesses. Understanding this distinction is fundamental to correctly identifying qualified providers.  

It is important to note that there is no single, official, government-maintained list that allows consumers to search for all SAA-accredited installers specifically within Queensland. Instead, identifying and verifying qualified providers involves understanding the current standards and utilizing specific tools and verification methods. This report aims to provide Queensland consumers with the necessary knowledge and practical strategies to confidently navigate this process. It will detail the roles of SAA, NETCC, the CEC’s product approval scheme, and Queensland’s mandatory electrical licensing requirements. Subsequently, it will outline methods for finding potential providers and, crucially, verifying their credentials and the products they offer, concluding with essential checks before entering into any contract.  

2. Understanding the Current Accreditation & Licensing Landscape in Queensland

Ensuring a high-quality, safe, and compliant solar PV and battery storage installation in Queensland necessitates verifying credentials across several distinct layers. These involve the individual performing the installation, the business selling the system, the specific components used, and mandatory state-level electrical licensing. Each layer plays a critical role in the overall integrity and eligibility of the system.

2.1. Solar Accreditation Australia (SAA): Accrediting the Installer (The Individual)

Solar Accreditation Australia (SAA) is now the designated national body responsible for the accreditation of individuals who design and install solar PV and battery storage systems. This function was previously managed by the Clean Energy Council but fully transitioned to SAA in May 2024.  

SAA accreditation for the individual installer who completes or supervises the installation is a mandatory requirement for the system owner to be eligible to claim STCs, often referred to as the ‘solar rebate’. Without this accreditation, the financial benefits associated with STCs cannot be accessed.  

Crucially, SAA accreditation applies only to individual persons, not to companies or businesses. While companies employ SAA-accredited individuals to perform the work, the company itself cannot hold SAA accreditation. Consumers should be wary of any business claiming to be “SAA Accredited,” as this indicates a misunderstanding or misrepresentation of the scheme.  

To achieve and maintain accreditation, installers must meet stringent requirements. This includes completing specific training modules, adhering to all relevant Australian Standards (such as AS/NZS 5139 for battery installations ), complying with local grid connection rules, and following the installation requirements of the accreditation scheme. Furthermore, accredited installers must meet strict on-site attendance requirements, being physically present during critical stages: job setup, a mid-installation check-up, and the final testing and commissioning. Photographic evidence documenting their presence at these stages, including date, time, and geolocation data, may be required for compliance verification.  

2.2. New Energy Tech Consumer Code (NETCC): Approving the Seller (The Business)

The New Energy Tech Consumer Code (NETCC) is a voluntary code of conduct specifically designed for businesses (retailers or sellers) involved in the sale of ‘New Energy Tech,’ which includes solar PV systems, battery storage, EV chargers, and other emerging technologies. Although participation is voluntary, the code is administered by the Clean Energy Council and is authorised by the Australian Competition and Consumer Commission (ACCC).  

The primary goal of the NETCC is to establish consumer protection standards that go beyond the minimum requirements set by Australian Consumer Law. It covers the entire customer journey, setting standards for ethical sales and marketing practices, clear and comprehensive quotes and contracts, safe and timely delivery and installation, fair warranty terms, and effective after-sales support and complaints handling processes.  

While choosing a NETCC Approved Seller is not mandatory for STC eligibility in the same way SAA accreditation is for the installer, it is highly recommended. Businesses that become signatories commit to upholding these higher standards. Importantly, NETCC Approved Sellers are obligated to use SAA-accredited installers for the physical installation work and must use products (panels, inverters, batteries) that are approved by the Clean Energy Council. This commitment provides consumers with an added layer of assurance regarding the quality and compliance of both the installation service and the components used.  

The NETCC program officially replaced the CEC’s former “Approved Solar Retailer” (ASR) program on 1 February 2023. Consumers may still encounter references to the ASR program in older documentation or marketing materials , highlighting the importance of understanding this transition. The NETCC program has seen significant uptake, with over 1,500 businesses across Australia becoming signatories.  

The existence of the NETCC program serves as a valuable initial filter for consumers. Because Approved Sellers have undergone an assessment process and committed to higher operational and ethical standards , searching the NETCC directory first can streamline the process of finding reputable businesses. These businesses are more likely to adhere to best practices, use qualified personnel (SAA accredited installers), and install compliant equipment (CEC approved products) , simplifying the consumer’s initial search phase compared to navigating the broader market.  

2.3. Clean Energy Council (CEC): Approving Products & Administering NETCC

While the CEC no longer accredits individual installers, it retains crucial roles within the rooftop solar and battery sector. Its most significant function for consumers and installers is maintaining the official lists of approved products. These lists cover PV modules (panels), inverters, and batteries that have been tested and verified as meeting relevant Australian Standards.  

Using components included on these CEC-approved lists is mandatory for claiming STCs. Furthermore, grid connection agreements with electricity network distributors often require the use of CEC-approved components. It is vital for both installers and consumers to ensure that the specific make and model of panels, inverters, and batteries being installed are currently listed, as products can be added or removed (de-listed) over time. Checking these lists directly on the CEC website provides certainty.  

As mentioned previously, the CEC also administers the NETCC program for approved sellers.  

Additionally, the CEC offers company membership. However, this is distinct from both SAA installer accreditation and NETCC seller approval. While membership indicates support for the clean energy industry, it involves lower barriers to entry and is not considered a reliable indicator of installation quality or adherence to specific consumer protection standards compared to NETCC approval.  

2.4. Queensland Electrical Licensing: The Non-Negotiable Foundation

Underpinning all industry-specific accreditations and approvals is the fundamental legal requirement for electrical licensing in Queensland. Any individual performing electrical wiring work, which includes the installation of grid-connected solar PV systems and battery storage systems, must hold a current Queensland electrical licence issued by the state’s Electrical Safety Office (ESO).  

This requirement applies irrespective of whether the individual holds SAA accreditation or works for a NETCC Approved Seller. It covers grid-connected systems and generally extends to off-grid systems involving alternating current (AC) voltages of 50V or more, or direct current (DC) voltages of 120V or more. Battery system installations inherently involve electrical work requiring a licensed electrician.  

Engaging unlicensed individuals for electrical work is illegal and poses significant safety risks, potentially leading to electric shock or fire. Consumers have a responsibility to verify the electrical contractor’s licence number before any work commences. This verification ensures the work is performed legally and by someone qualified under state law.  

The interplay of these different requirements highlights that ensuring a compliant and high-quality installation involves multiple checks. The individual installer needs both SAA accreditation (for STCs and industry standards) and a Queensland electrical licence (for legal and safety compliance). The business selling the system should ideally be a NETCC Approved Seller for enhanced consumer protection and assurance of best practices. Finally, the core components – panels, inverter, and battery – must be on the CEC’s approved product lists. Failure to meet the mandatory requirements (SAA accreditation, QLD licence, CEC-approved products) can jeopardise STC eligibility, grid connection approval, system safety, and legal compliance. Opting for a non-NETCC approved seller, while not automatically disqualifying, removes a layer of assured consumer protection and recourse.

3. How to Find and Verify Approved Solar and Battery Providers in Queensland

Given the multi-layered compliance landscape and the absence of a single, comprehensive government directory, a strategic approach is needed to find and verify solar and battery providers in Queensland. The recommended process involves using dedicated directories to identify potential businesses and then rigorously verifying the credentials of both the business and the specific individuals involved.

3.1. Primary Method 1: NETCC Approved Seller Directory (Recommended for Businesses)

The most effective starting point for finding reputable businesses is the official NETCC “Find an Approved Seller” directory. This tool is accessible via the NETCC website at https://www.newenergytech.org.au/find-an-approved-seller.  

Users can search this directory by location, entering a specific Queensland suburb or postcode. Crucially, the tool allows filtering by the type of services offered, enabling users to specifically select businesses that provide both Solar PV and Battery Storage systems. The search results are typically displayed as a list or map of businesses meeting the criteria.  

The primary advantage of using this directory is that it lists businesses that have voluntarily committed to the higher consumer protection standards outlined in the NETCC. These businesses are also required to use SAA-accredited installers and CEC-approved products, providing a degree of pre-qualification. With over 1,500 signatories nationally, the directory offers a substantial pool of potential providers.  

However, it’s important to remember that this directory lists businesses (sellers), not every individual SAA-accredited installer. Furthermore, participation in the NETCC program is voluntary, meaning some competent and reputable installers or businesses may not be listed. Therefore, while an excellent starting point, it should not be the sole resource used.  

3.2. Primary Method 2: Master Electricians Australia (MEA) Directory

Another valuable resource is the “Find a Master Electrician” tool provided by Master Electricians Australia (MEA) , available at https://www.masterelectricians.com.au/find-master-electrician/. MEA is an industry association for electrical contractors.  

This tool allows users to search for member businesses based on specific services and location. Users can select multiple services from an extensive list, including relevant options like “Solar,” “Battery Energy Storage,” and potentially “CEC Accreditation” (though the exact meaning of this filter in the current context may need clarification with the provider, it likely relates to familiarity with CEC requirements or product lists). Users then enter a Queensland location (suburb or postcode) and specify a search radius (10km, 50km, or 100km) to find local contractors.  

Using the MEA directory can identify local electrical contractors who are members of the association and have committed to a code of ethics, with access to technical and safety support resources. It provides an alternative searchable database filtered by specific electrical specialisations, including solar and battery work.  

Similar to the NETCC, MEA membership is voluntary, so the directory does not encompass all qualified electricians or solar installers in Queensland. Finding a contractor through this tool still necessitates independent verification of their specific SAA accreditation for solar/battery work and their current Queensland electrical licence status.

3.3. Verification Step 1: Checking SAA Accreditation (For Individuals)

Once potential providers (businesses) have been identified, the critical step is to verify the accreditation of the individuals who will be responsible for the system design and installation. This is done using the SAA “Accreditation Status Check” tool , found at https://saaustralia.com.au/accreditation-status-check/.  

This tool is designed purely for verification, not for searching a list of installers. To use it, the consumer must first obtain the full name or, preferably, the SAA accreditation number of the specific installer(s) from the potential solar company. It is essential to ask the company for these details for the individuals who will physically perform or directly supervise the work on-site. Entering these details into the tool confirms whether the individual holds current SAA accreditation and is therefore qualified under the scheme required for STC eligibility.  

3.4. Verification Step 2: Checking Queensland Electrical Licenses

Parallel to verifying SAA accreditation, it is imperative to confirm that the electrical contractor (business) and/or the individual electrician performing the work holds a valid Queensland electrical licence. This is verified using the official Queensland Government Electrical Licence Search tool, managed by the Electrical Safety Office (ESO). The tool can be accessed via the ESO website at https://www.electricalsafety.qld.gov.au/electrical-license-search or directly through the public search portal at https://rapid.appianportals.com/public_licence_search.  

Users can search the database using the electrical contractor’s business name or their specific licence number. The search confirms if the licence is current and valid for the type of electrical work being undertaken. This check verifies the legal right of the contractor to perform electrical work in Queensland, which is a fundamental safety and compliance requirement that cannot be overlooked.  

3.5. Secondary Resources (Use with Caution)

Beyond the primary NETCC and MEA directories and the essential SAA/QLD Licence verification tools, consumers may encounter other resources:

  • Third-Party Directories & Comparison Websites: Numerous commercial websites (e.g., SolarQuotes , Solar Directory , ENF Solar ) list solar installers, often searchable by location. Some, like SolarQuotes, state they vet installers they refer. While these can be useful for identifying local businesses, consumers must exercise caution. Listing on such sites does not automatically guarantee current accreditation or quality. It is crucial to always independently verify SAA accreditation and QLD electrical licenses using the official tools described above, regardless of claims made on third-party platforms. Be mindful that commercial relationships may influence rankings or recommendations on these sites.  
  • National Electrical and Communications Association (NECA): NECA is another significant industry body representing electrical contractors. While NECA has member directories , publicly accessible search tools appear less specifically filterable by service (like solar/battery) and location compared to the MEA tool, based on available information. Consumers seeking NECA members may need to contact the Queensland branch directly for assistance.  

The existence of separate systems for installer accreditation (SAA), business approval (NETCC), product approval (CEC), and state licensing (QLD ESO), along with various voluntary industry memberships (MEA, NECA) and commercial directories, means there is no single, unified source for finding and verifying providers. Consumers must utilize a combination of these tools to build a complete picture. Relying solely on one directory or skipping the verification steps carries significant risks regarding compliance, quality, and eligibility for incentives.

Furthermore, the lack of a publicly searchable database of all SAA-accredited installers by location places the primary burden of verification onto the consumer. Unlike searching for a NETCC Approved Seller business, finding and verifying the specific SAA-accredited individual requires proactively requesting their details (name and/or accreditation number) from the potential solar company and then using the SAA verification tool. Similarly, verifying the QLD electrical licence requires obtaining the contractor’s details first. This active verification process is an essential part of consumer due diligence.

4. Essential Checks Before Signing a Contract in Queensland

Identifying potential solar and battery providers using the directories and verification tools is a critical first phase. However, comprehensive due diligence must be performed before signing any contract to ensure the chosen provider meets all requirements and offers a suitable solution.  

4.1. Confirm Credentials

Before proceeding, re-verify all essential credentials:

  • SAA Accreditation: Obtain the full name and SAA accreditation number(s) for the specific individual(s) who will be responsible for the system design and the on-site installation supervision (including setup, mid-install check, and commissioning). Use the SAA status check tool (https://saaustralia.com.au/accreditation-status-check/) to confirm their accreditation is current and covers the relevant installation types (e.g., grid-connect solar, battery storage).  
  • NETCC Approval (Business): If engaging a solar retailer/company, confirm if they are listed as a NETCC Approved Seller using the NETCC finder tool (https://www.newenergytech.org.au/find-an-approved-seller). Choosing an Approved Seller provides access to enhanced consumer protection mechanisms and dispute resolution pathways.  
  • QLD Electrical Licence: Request the Queensland electrical contractor licence number for the business undertaking the work, as well as the licence number of the specific electrician(s) who will be performing the electrical installation. Verify these licences are current and valid using the QLD ESO Electrical Licence Search tool (https://www.electricalsafety.qld.gov.au/electrical-license-search or https://rapid.appianportals.com/public_licence_search).  

4.2. Verify Product Approval

Ensure that every major component offered in the quote – specifically the solar panels (modules), the inverter(s), and the battery system – is currently listed on the Clean Energy Council’s approved product lists. The quote should clearly state the manufacturer and exact model number for each component. Ask the provider for links to the listings or check them independently on the CEC website (https://cleanenergycouncil.org.au/industry-programs/products-program). Using components not on these lists will render the system ineligible for STCs and may violate grid connection agreements.  

4.3. Obtain and Compare Multiple Detailed Quotes

Do not rely on a single quote. Obtain at least two, preferably three, detailed written quotes from different qualified providers to compare offerings and prices. A professional quote should be comprehensive and transparent, avoiding handwritten or vague proposals. Key elements to look for in each quote include :  

  • Full business details: Name, address, phone number, ABN, and crucially, the QLD Electrical Contractor Licence number.  
  • Installer details: Name and SAA accreditation number of the responsible installer(s).
  • Itemised pricing: Clear breakdown of costs (including GST) for all components (panels, inverter, battery, mounting structure, cabling, isolators, etc.) and labour.  
  • Component specifics: Exact quantity, manufacturer (brand), and model number for panels, inverter, and battery.  
  • System specifications: Total solar array size (kWp) and battery usable capacity (kWh).  
  • Performance estimate: An indication of the expected energy generation and potential savings, including assumptions made.  
  • Warranty details: Clear statements outlining the duration and coverage of product warranties (panels, inverter, battery) and the installer’s workmanship warranty.  
  • STC calculation: Explicit mention of the STC discount applied to the total price.  
  • Timeline: An estimated schedule for supply and installation.  
  • Payment terms: Deposit requirements, progress payments, and final payment schedule.  
  • Substitution policy: Terms regarding component substitution if quoted models become unavailable (should require customer agreement and be for equivalent or superior specification).  

The level of detail and clarity in the quote often reflects the provider’s professionalism. A thorough, itemised quote suggests a meticulous approach, whereas a vague quote might obscure costs or allow for unwelcome variations later. NETCC standards specifically require clear and comprehensive quotes and contracts , reinforcing the link between quote quality and provider standards.  

4.4. Understand Warranties and After-Sales Support

Warranties are a critical aspect of the long-term value and security of a solar and battery investment. It is essential to understand the different warranties involved and who is responsible for honouring them. Key warranties include:  

  • Solar Panel Product Warranty: Covers defects in materials and workmanship (typically 10-25 years).
  • Solar Panel Performance Warranty: Guarantees a minimum power output level over time (typically 25 years, often with tiered degradation).
  • Inverter Warranty: Covers the inverter unit (typically 5-10 years standard, often extendable for a fee).
  • Battery Warranty: Covers the battery (typically 10 years, but often includes important conditions related to cycles, throughput, or depth of discharge).
  • Workmanship Warranty: Covers defects related to the installation itself (NETCC Approved Sellers must provide a minimum five-year whole-of-system warranty, which often includes workmanship , but always confirm the specifics).  

Clarify the process for making a warranty claim for each component and for the installation work. Understand whether the installer/retailer manages the claim process with the manufacturer or if the consumer needs to deal directly with the manufacturer. Consider the risk of the installer/retailer going out of business; while Australian Consumer Law (ACL) provides recourse through the manufacturer for product faults, claiming can be more complex. Keeping detailed records of all components and manufacturers is vital. The complexity of these multiple, overlapping warranties, reliant on the longevity of different entities (installer, retailer, manufacturer), underscores the importance of choosing established, reputable providers. The NETCC’s mandated 5-year whole-of-system warranty offers a baseline level of protection , but scrutiny of the specific terms and the provider’s stability remains crucial.  

4.5. Review the Contract Carefully

Before signing, meticulously review the final contract. Ensure it accurately reflects all terms agreed upon in the final quote, including component models, pricing, warranties, payment schedule, and installation timeline. Pay close attention to clauses regarding potential delays, component substitutions, dispute resolution processes, and any exclusions or limitations. Do not sign if there are discrepancies or unclear terms.  

4.6. Check Installer/Seller Experience and Reputation

Assess the provider’s track record and stability:

  • Business History: How long has the company been operating in the solar/battery industry? Look for businesses with several years of experience and an established local presence.  
  • References: Ask for contact details of previous customers in Queensland who have had similar systems installed. Speaking to references can provide valuable insights into their experience with the company’s service, communication, and post-installation support.  
  • Reviews: Check online reviews on platforms like Google or industry-specific sites (e.g., SolarQuotes), but interpret them critically, looking for patterns rather than isolated comments.  
  • Installation Team: Clarify whether the company uses its own employees for installation or relies on subcontractors. In-house teams often provide greater accountability and consistency.  

4.7. Queensland Specific Checks

Confirm the provider is familiar with local requirements:

  • Network Connection: Ensure the installer understands the specific grid connection application processes and technical requirements for Energex (South East QLD) or Ergon Energy (Regional QLD). They should typically handle the network connection agreement application on the customer’s behalf.  
  • Emergency Backstop Mechanism: If the proposed system (solar PV and/or battery) has an inverter capacity of 10 kilovolt-amperes (kVA) or greater, verify the installer is aware of and compliant with the requirement to install a generation signalling device as part of Queensland’s emergency backstop mechanism, implemented from February 2023.  

5. Conclusion: Your Checklist for Choosing a Queensland Solar & Battery Provider

Selecting the right provider for a solar PV and battery storage system in Queensland is a significant decision that requires careful research and verification. Due to recent changes in industry accreditation and the multi-layered nature of compliance, consumers must be proactive in their due diligence.

To summarise the recommended approach, consider the following checklist:

  1. Understand the Landscape: Recognize that SAA accredits individuals, NETCC approves businesses (voluntary), CEC approves products, and a QLD Electrical Licence is mandatory for electrical work. Be aware that “CEC Accredited Installer” is outdated terminology.  
  2. Identify Potential Providers: Use the NETCC Find an Approved Seller tool (https://www.newenergytech.org.au/find-an-approved-seller) as a primary resource for finding businesses committed to higher standards. Supplement with the MEA Find a Master Electrician tool (https://www.masterelectricians.com.au/find-master-electrician/) if desired. Use other directories with caution.  
  3. Verify SAA Accreditation: Obtain the name(s) and SAA accreditation number(s) of the specific individual(s) designing and installing the system. Verify their current status using the SAA tool (https://saaustralia.com.au/accreditation-status-check/).  
  4. Verify QLD Electrical Licence: Obtain the electrical contractor licence number(s) for the business and individual(s) performing electrical work. Verify their status using the QLD ESO tool (https://www.electricalsafety.qld.gov.au/electrical-license-search).  
  5. Verify CEC Product Approval: Ensure all quoted panels, inverters, and batteries (by specific model number) are on the current CEC approved lists (https://cleanenergycouncil.org.au/industry-programs/products-program).  
  6. Get Multiple Detailed Quotes: Obtain at least 2-3 itemised, written quotes from different verified providers.  
  7. Compare Quotes Thoroughly: Analyse component details, system size, performance estimates, all warranty terms (product, performance, workmanship), STC inclusion, timelines, and payment terms.  
  8. Assess Warranties & Support: Understand warranty coverage, claim processes, and who provides support. Consider provider stability.  
  9. Review Contract: Ensure the contract matches the final quote and all terms are clear before signing.  
  10. Check Reputation & Experience: Investigate the provider’s history, check references, and read reviews critically.  
  11. Confirm QLD Network Compliance: Ensure the provider understands Energex/Ergon connection rules and requirements for larger systems (>10kVA) if applicable.  

While the fragmented nature of accreditation and approval places a verification burden on the consumer, diligently following these steps significantly increases the likelihood of engaging a qualified, compliant provider. This methodical approach helps ensure the installation of a safe, high-performing solar and battery system that meets Australian standards, Queensland regulations, and is eligible for available government incentives. A reputable provider should be transparent, willing to provide all necessary credentials and documentation, and answer questions clearly throughout the process. Should issues arise with a provider, particularly a NETCC Approved Seller, avenues for complaint resolution exist via the NETCC program administrators or Queensland’s Office of Fair Trading.
